CONNECTING-ROD.

Specification of Letters Patent.

Patented July 20, 1920.

. Application filed may a, 1919. Serial No. 294,415.

To all who m'it may concern:

Be it known that I, JULIUs KINDERVATER,

a citizen of the United" States, residing at Closter, in the county of Bergen and State of New Jersey, have'invented certain new and useful Improvements in Connectingnected ata single point on the crank. It is to this particular type of tool that my in vention hasreference,alth'ou'gh its application is equally well suited for any form of tool or-mechanism having reciprocating pistons.

Among the objects of the invention is to providev an improved rod .which shall be simple and rugged in construction, cheap to manufacture, and easy to assemble, and which can be readily detached from the crank when occasion requires.

To this end I propose toconstruct the rod of two wholly separate and independent sections,lying'side'by side, said sections having at one endoi'ntegral lateral projections, together forming a transverse journal for connection withfthe piston, and at the other end provided with enlarged semicylindrical portions together constituting a split tubular bearing for the crank. I,

further propose tofso pivot the rod sections to the piston. that they may partake of relative 'swinging movement around a common axis, thus separating the said split bear.-

ing so that it may be removed from; the

crank,,and to so construct such bearing on one rod that it serves as a g journal for the bearing of theother rod.

In order that the invention may be readily understood, reference is had to the accompanying drawings formingpart "of this specification and in which ing the' pair of my ;i m 'pro ved connecting Figure 1 is sectional fsideelevation show- Fig. 2 is an edge the left of Fig. 1;

Fig. 3 is a' plan view in Fig. 1;

Fig. 4 is a transverse section through the crank connection substantially on the line H of Fig. 3

Fig. 5 is a perspective view of one of the yokes for attaching the rod to the piston;

Fig. 6 is a transverse section on the line 6-6 of Fig. 1;

elevation looking from of the parts shown Fig. 7 is a sectional view taken substantially on the line 7 of Fig. 3; Fig. 8 is a view similar to Fig. 6 but showing' a slightly modified construction;

Figs. 9 and 10 are sections on the lines 99 and 1()10, respectively, of Fig. 8,-

split longitudinally on a central plane so as to form two wholly independent separable sections. The two sections of the rod 3 are secured together by a single screw 7. while the sections of the rod 4 are united by a series of three screws 8, (see Fig.

The connecting rod 4 is Yssha ped in plan as shown in Fig. 3, and the ends of each branch of each section are curved into semicylindrical form as indicated at 6. The eX treme ends abut as shown at 10 so that the entire structure forms a split tubular bearing havingtwo limbs or branches.

The ends of each section of the rod 3 are enlarged to form semi-cylindrical portions 9, the ends of each abutting as at 11 to form a closed tubular hearing. The meeting edges of the semi-cylindrical portions 9 are preferably rabbeted to form overlapping tongues 9 and 9 as clearly shown in Fig. 7

The split tubular bearing formed by the semi-cylindrical portions 9 of the connecting rod 3 is extended transversely to a shown), disposed at 60 ofythefjournal portion 24' and the two sec of the branches- 6 othe connecting rod 4, and is provided at its ends with annular" grooves or seats 12, separated by an inter-- vening thickened portion 1 3 (.see Fig. &), By reference to Figs. 3 and 4 it will be seen that the curved portions 6 embrace the-tubw lar bearing 9 and lie in the grooves 12 at the same point', the bearing portion oi' 'one rod serving as a ournal for and surrounded by the bearing portion of the other rod.

In order to provide means for conveniently attaching the connecting rods to the pistons, each section of each rod is formed at its end with an'i'ntegral transversely extending portion 14: having a cylindrical outer surface,such portions, when assembled in pairs, as shown: in Fig. l, constituting journals or. pivot pins projecting at'each side ofthe respective frods. In order to attach I I e v connecting rod provided at one end with a these journals to the respective piston I provide infeach casea pair'of yokes 16 having base flanges 17' secured to the piston by means of rivets 19. 'The' yokes 1 6' are pro vided at their inner: sides with trough-like projections 18, which projections abut as,

shown in Figs. 2 and 3' to gage the proper spacingof the yokes; It will be understood that inassembling the yokes areslipped' over thef'ends of the journal 14" and are then" riveted to-the piston after the partshave beenplacedin position. 7 Y

In orderto permitthesections o fthe rods to have relative anddndependent swinging movement on the journal portions 1 1, these portions arecutaway or beveledat one side beyond the axis thereof as indicated at 15 V in Fig. 1*. It will'th'erefore be apparent that when the screws 7Jor 8 are removed, the two' sections] of either rodmay be swung apart'as indicatedinfdottedlines in Fig. 2 so that the *nect-ing rod. is indicated 2303 a 10 1 W,

rods may be'thus disconnected from the crank. It will therefore besee'n that each.

ro'd'sectionfofanyj pair is capable of relative plvotal movement about a common ax s, such axis being the same asthat aboutiwhich the rod osc'illates as a whole"when noperat on.

In Figs. 8to11yinclusive, I havefshown a slightly modified construction embodying" the same principles, In these viewstheconsemi-cylindrical hearing or journal portion 24 isformedjintegral' with and extends transversely ofeach rod section. A pivot pin27t'extends through the hollow bore; 25'

' tionsfof the journal and rod are held to:

proposed to disconnect the "rod, from the crank in'the same manner as shown in Flg. 1',- vizi; by sw nging the sections apart about theirypivotal: axis, and to. this end the extreme edge of each portion 24; at one side of the ax is is cut away 'or shortenedas'illus- In both modlfications, however, the same 7 principle of construction is employed, viz., thefmounting of the rod sections sothat they may have a relatlve swinging 1 movement about a common pivotal axis to permit the separation of their inner ends." In both cases, also, integral, transversely extending journal portionsare formed onthe rod'sections andthese portionsare cut away at one side of'the pivotal; axis so as to permit lthe above described relative swing ng movement.

' What I claim'i's 1. The coinbination with a piston, of a cyliii dric portion extendingtransversely of the roar and forming an integral journal,-

and means for connecting such cylindric portion to V the piston, such means comprising a pair of nde'pendent one piece yokes secured to thep'istonaeach yoke completely encircling said-cylindrical portion." 7 I 2.

5. The combination with a piston and crank, of a connecting rod therefor, saidrod being split longitudinally into two wholly separable sections, said sections being shaped at one end to embrace said and being independently pivotally connected at the other end with said piston so as to be capable of relative, swinging movement about a common axis coinciding with that of said pivotal connection.

6. The combination with pistons and a common crank, of connecting rods oining said pistons with said crank, each of said rods being split longitudinally into two wholly independent sections, each section having an enlarged semi-cylindric portion so as to form a tubular split bearing at one end of each of said rods, the bearing of one of said rods being adapted to be journaled on said crank, and the bearing of the other of said rods being adapted to be journaled on the bearing of the first mentioned rod, and means for pivotally connecting the opposite ends of the pairs of rod sections to said pistons so that the members of each pair may swing relative to the pistons and to each other, said pivotal connecting means being constructed to prevent separation of the rod sections adjacent the pistons.

In testimony whereof I aflix my signature.
